Description
Technical field
The present invention relates to technical field of livestock husbandry, specifically the method for a kind of high-quality boar breed system hybridization market pig.
Background technology
The initial stage eighties in last century to the nineties, western countries' pig industrys such as American and Britain mainly carry out the production of " ocean ternary " barren sow using Large White, Landrace and duroc as boar, after breed system occurs, the market share of a few years Swine Production 80% is just occupied by this new production model. Compared with existing pig kind, breed system pig has a bigger species the advantage, and tradition quality pigs kind often can only embody such as one, two advantages such as lean meat percentage height, fast growths, and breed system then can embody a concentrated reflection of multiple advantage. The French Academy JeanNAVEAV utilize China's Taihu pigs (prunus mume (sieb.) sieb.et zucc. mountain pig and Jiaxing Black Pig) make female parent, through the work of 8 years, cultivate " wet nurse " newly maternal, and with P76 paternal line corss combination; Also has PIC company, also utilize the performance that Taihu pigs reproductive capacity is high, meat is good to cultivate to make new advances maternal " Kang Beier ", and with 402 paternal hybridization, forming fixing 5 is supporting produce assorted excellent pig, thus it is low to solve reproductive capacity all to some extent, the contradiction of meat difference.
Berkshire (Berkshire) meat fat has both type pig variety. Before and after 1770, Britain introduces Chinese Pigs, Siam pig and local pig hybridization, within 1860, is substantially bred as, for lard type kind. After World War II, change and educate for lean meat species. Pig body body length and wide, nose is short and recessed, and ear uprightly or slightly before inclines, chest depth hip breadth, by hair black, and has " six is white " (lower extremities, nose, tail broom for white) feature. Adaptive faculty is strong, and growth is fast, precocious. Reproductive capacity is on the low side, and average every tire produces 9 young left and right. China 19 introduces the end of the century, once economizes in Liaoning, Hebei etc. and local sow hybridization, played effect to cultivating new varieties.
Duroc, originates in the U.S., is bred as by the red hair Berkshire that USA New York red hair duroc, the western red live pig in pool of New Jersey and health are Di Gezhou at Northeastern United States the sixties in 19th century.Being originally lard type, be meeting the market requirement later, upgrading is bacon hogs. This pig kind established breed standard in 1880, was one of famous bacon hogs kind of contemporary world.
Binary pig is a kind of Hybrid of pig, is formed by two boar hybridization, is known as binary pig. Two-way cross, also referred to as single-cross, is namely hybridized by two kinds or strain, gained first cross kind. Owing to Heterozygosity is big, having obvious heterosis, hybrid vigor, growing way is fast, fattening effect good, so this hybridization Application comparison is extensive.
Outer ternary bacon hogs is promoted general, technology maturation, and yield increases, but it is inconspicuous to there is weight-improving effect, the shortcoming that fat and lean meat ratio is uneven.
Summary of the invention
For above-mentioned weak point of the prior art, it is desirable to provide a kind of weight-improving effect is obvious and the method for the uniform high-quality boar breed system hybridization market pig of fat and lean meat ratio.
For solving above-mentioned technical problem, the method for the high-quality boar breed system hybridization market pig of the present invention, comprise the following steps:
A) using without the halothane recessive gene Berkshire the first male parent as breed system, maternal as the first of breed system using duroc, hybridization obtains bar Du cross-bred pig;
B) the second male parent being breed system with Landrace, Large White is the second maternal of breed system, and hybridization acquisition is grown up binary pig;
C) hybridizing the bar Du cross-bred pig terminal male as breed system of acquisition in selecting step A, what in step B, hybridization obtained grows up binary pig as breed system terminal female parent, and hybridization obtains high-quality commercial pig.
Further, the described Berkshire of recessive gene without halothane is that lean meat percentage is high, Meat Quality is good, appearance traits is consistent and the Berkshire of recessive gene without halothane of anti-stress.
Further, described duroc is body constitution stalwartness, strong stress resistance, fast growth, efficiency of feed utilization is high, carcass lean meat percentage high, meat is good duroc.
Further, described Landrace be that lower limb buttocks is plentiful, strong-limbed, Landrace that back of the body waist is straight.
Further, described Large White is that build is tall and big, back of the body waist is straight, the Large White of spuare rump.
The method of the high-quality boar breed system hybridization market pig of the present invention, the fast growth of its high-quality commercial pig, up to 726g/d, fat and lean meat ratio uniform, without PSE meat, Meat Quality is good, it is possible to go out fertilizer, reliable product quality in advance, market prospect is good, can shift to an earlier date 10-15 days and go out fertilizer, improves production efficiency.
Detailed description of the invention
Below the technical scheme in the embodiment of the present invention is clearly and completely described. Obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment 1 cross combination test and combining ability test
